Piston skirt is a key problem in the processing piston turning. This paper focus on the characteristic of noncircular turning, put forward a sort of configuration with two Linear Motor installed back to back, developed a high frequency micro-feed Linear servo carriage system. The carriage structure is simple , operation and commissioning easy. For China' s high-grade piston processing provides a set of idea processing equipment.%活塞裙部异型外圆加工是活塞加工的关键,文章针对活塞裙部非圆加工的特点,提出一种由两套直线电机背对背安装的结构形式,研制出一种可以实现高频响微进给大推力的直线伺服刀架.该刀架结构简单、调试操作方便,为我国高档活塞的加工提供一种有效的加工设备.
